426 stroker dyno results

[Boxer]

I had Hughes do a 426 stroker for me, I had them ship all parts to me and I coated every part inside and out with ceramic coatings.
We had goals of obtaining around 600hp on pump gas. We cleared the 600 mark by 21HP, and made 609ft lbs torque. I only have the rough draft sheets, but Dave is going to do a formal write up on there web page after there show on 3/15 - 3/16.
They did this dyno with a 750 carb and 1 3/4 headers. He feels this was under carbed and under sized headers. He also feels that with the write combo it may make close to 650hp.
I am not the most knowledgeable about engines but know enough to get myself in trouble. I will give a list of all the parts that I know of and try to answer any questions. I am also going to sell this motor, not sure of price yet but I am sure it will be @ $20g's. I will work on a solid price next week with Dave after the show.
Race prep 360 block, 426 race kit, eddy stage 3 heads, Her6468al-7 roller cam, beehive springs, 1.6 rockers, super victor stage 2 ported intake, 10:3 pistons, special Hughes oil pan, and we did the ceramic coatings at our shop, PPC.

I agree, It needs more carb (1000cfm 4150 or a 1050 4500 series) and bigger headers like 1-7/8"

Why are you selling the motor all ready ?

Boxer, can you give us more detailed info on your coatings (ie. actual materials, benefits (and cons if any), costs, etc.)? Did the pistons get two separate coatings, one for the top and one for the skirts? When parts like bearings are coated, do they need to be scuffed off since the material is impregnated in the metal? If you have a site that answers all these questions (especially the cost break down), that would be helpful. Looking forward to your reply.

selling the motor because i want to run a 150-200 shot of juice on it. This fact was not discussed until late in the build. Evidently the piston height is to small and they recommended against it. Not to mention that with that mush hp it is pushing the integrity of the block itself. I then found a R3 block and achieved 442 cid with out stroking, and will be able to run a shot of juice.

Can't remember all the other questions, but yes we used three coatings on the pistons. Thermal barrier on top, thermal dispersant on skirts, and a thermal barrier w/oil shedding on underside. We have a web page www.powdercoatingwi.com.

Missed the bearing ?. The coating can be banished to zero tolerance but still remain on the bearing.

Whoa....20g's for a small block stroker!!! thats some serious cake..

Not sure of exact price, I need to sit and go through everything. I just threw that out, if I remember it is a round there maybe not that much. It will be just what I have into it.
